WINDOW STRUCTURE.

Application filed August 4, 1927. Serial No. 210,541.

My invention relates to an improved closure means and more particularly to a door or window having a frame in which a pane is mounted and to which a second pane is detachably fastened spaced from said' first mentioned pane. My invention primarily relates to a storm window of a new and improved type embodying all the advantages of the old type of storm window in which the two glass panes were each mounted in a separate sash, and yet is free of the various objections found in the old type referred to.

In the average building, seventy-five per cent of the heat loss is through window glass which may be largely eliminated by providing windows having two panes mountedin spaced relation to each other. If desired, the panes may be of glass, in which case they will not materially affect the vision or passage of light therethrough. Such a structure affords a substantial saving of fuel and produces a room practically free of drafts and one which is more evenly heated.

One of the objects of my invention is to rovide a closure, such as a door or win ow, which has two panes, preferably of glass, mounted on a single sash, one of said panes being detachably secured.

Another object of my invention is to provide a window comprising a sash of the customary type having a pane permanently mounted therein with a second pane positioned to engage the side thereof, and having fasteners mounted in the side of said sash and adapted to releasably engage and hold said second pane in position.

Another object of my invention is to provide a removable pane for doors or windows of customary type, and fasteners therefor, said pane being readily installed and detach ably held in position on either the inside or outside face of the sash.

Another object of my invention is to provide a detachable pane for a pair of slidable window sashes having permanently mounted panes therein, said detachable panes being mounted on the faces of said sashes. each positioned outside the path of travel of the other sash whereby interference is avoided when the sashes slide past one another.

These and other objects are accomplished by means of the arrangement disclosed on the accompanying sheet of drawings, in which Figure 1 is a cross sectional view. of a double sash window, each sash of which is equ pped with my improved window pane positioned on the inside;

Figure 2 is a similar view showing a double window sash construction similar to that shown in Figure 1, in which my improved window pane is attached to the outside thereof;

F igure 3 is a fragmentary elevation showing the attaching clips for holding the pane 66 detfichably against the face of the window sas Figure 4 is a perspective view of a modified form of attaching clip;

Figure 5 is a fragmentary sectional view of a double sash window showing an application of the clip shown in Figure 4;

Figure 6 is a similar sectional view in which the second window pane is inset with respect to the sash and showing application of a similar clip and also a spring plate release member.

The various novel features of the invention will be apparent from the following description and drawings and will be particularly pointed out in the appended claims.

Referring to the drawings, it will be noted that my invention is to be applied to a closure of customary type, 'such as a window comprising two slidable sashes 10 and 11 positioned in a frame 12 and mounted in the usual manner. Sash 10 constitutes the lower portion of the closure and has on the outer surface a recess 13 in which is positioned a glass pane 14 held by putty 15 or any other suitable means. The upper sash is constructed in a similar manner, being provided with a pane 16 held by putty 17 and having a portion 18 engaging the lower sash along the surface 19 whereby the sashes in the position shown in Figure 1 eifectivel close the opening in the window frame. e upper and lower sashes are provided with a lock 20 comprising a locking lever 21 and a loop 22 of the customary type. In the form of my invention shown in Figure 1, the sec ond pane 23 is of glass and is positioned against the inner face of the sash 10, engaging edgewise the metallic plates 24. These plates are held by any suitable means, such as screws 25, against the side of the sash 10 and are provided with a second plate 26 adapted to pivot when the screw 25 is loose but to be firmly held in position when the screw 25 is tightly screwed down. The

second plates 26 are pivoted eccentrically so that in one position they may present a portion which will overlie the glass pane 23 when in mounted position to effectively secure the same in position. However, the pane may be readily removed by merely loosening the screw 25 and turning the plate 26 to its opposite position where no portion thereof overlies the pane 23. The upper sash 11 is provided with a similar pane 23 and one which is mounted in the same fashion as that on the lower sash 10, the only difference being that it is provided with a cut-away portion at 27 so that it may arch over the locking element 22.

Referring now to Figure 2, corresponding parts bear the same reference numerals as those in Figure 1, the only difference being that this modification shows the pane 23 mounted'on the outside of the sashes 10 and 11, in which case the locking plates and screws are fastened on the opposite faces of the sashes.

It can be readily appreciated that this auxiliary window pane can be readily at tached to the customary type of window or door and may be of glass or any other suitable material for this use. Its value resides in the fact that it affords a dead air space in the window structure thereby providing all the advantages realized in storm windows and provides a structure which is free of all the objections in the old type of storm window. It may be quickly installed and after it is installed, the pane may bequickly removed and put back. Among the many advantages, it does not interfere with the visible quality of the window, it cuts down the heat loss, and eliminates drafts and all tendency of condensation of frost on the window. This invention permits free operation of windows at all times and the auxiliary glass can be put on and taken off from inside the house in actually a few seconds time. The auxiliary glass provides an unbroken surface permitting quick washing and is further a type WhlCh requires no upkeep, such as painting, puttying, etc. The fasteners for mounting the auxiliary glass are simple in structure and are inconspicuous, being preferably finished to match existing hardware.

A modified clip 28 of spring material may be used if desired, said clip having afiat base portion 29 which may be pivotally secured to the sash by a screw 30, having a seat or shoulder 31 for receiving and supporting the edge of the auxiliary glass and having a yieldable inwardly bent finger 32 for yieldably retaining said glass in position. In Figure 6 the auxiliar glass is inset within a groove 33 in the sasli and a similar spring retaining clip 34 applied. In addition, mounted within the groove at spaced points are spring release members 35, one of which is shown in Figure 6. When the clip 34 is withdrawn the release member 35 will press the glass outwardly into a position wherein it may be gripped by the hand. The release member has an exposed grip portion 36 whereby it may be hand operated if the glass is stuck in position.

I claim:

1. Closure means comprising a sash having a pane therein, a second pane spaced from said first pane positioned against the side of said sash, plates fastened to said sash engaging edgewise said second pane, and other plates movably mounted on said first named plates overlying said second pane and forming detachable fasteners therefor.
